Here's a cute story in the Washington Post about the efforts of sanitation crews in Mexico City to clean up ages-old deposits of chewing gum in the city's public spaces and dissuade citizens from engaging in such unsavory forms of littering in the future.
"We are going to see if we can convince them to use the trash cans," said [Ricardo Jaral Fernández, the city government's executive coordinator for the conservation of public spaces], who dreams of tidy bins emblazoned with the slogan: "Do you love El Centro? Then show it!"
I have to say, inappropriate disposal of gum thankfully isn't really a problem in the community I live in. What about yours?
